Blocks are modular areas that can be added to the right side of your Dashboard Page or to the right side of Course pages by either clicking on the "Customise this page" button or the "Turn Editing on" button within their respective locations. The "Add a Block" button can be found within the Sliding Navigation Drawer once these buttons have been enabled, below the "Site Administration" button.
